Solution
The correct option is C Cephaleuros
Sargassum seaweed is a brown free-floating algae that grows atop water and blooms in the Sargasso Sea. Chlorella is a freshwater, single-celled algae that grows in fresh water. Chlorella emerged over 2 billion years ago, and was the first form of a plant with a well-defined nucleus. It is thought to boost the immune system and help fight infection. It has been shown to increase the good bacteria in the gastrointestinal (GI) tract, which helps to treat ulcers, colitis, diverticulosis and Crohn's disease. Nostoc is genus of blue-green algae with cells arranged in beadlike chains that are grouped together in a gelatinous mass. Ranging from microscopic to walnut-sized, masses of Nostoc may be found on soil and floating in quiet water. Cephaleuros species are filamentous green algae and parasites of higher plants. In Hawaii, at least two of horticultural importance are known: Cephaleuros virescens and Cephaleuros parasiticus. Typically harmless, generally causing minor diseases characterized by negligible leaf spots, on certain crops in moist environments these algal diseases can cause economic injury to plant leaves, fruits, and stems.
Hence, the correct answer is option C.
